Summary

ABB Process Industries has developed a simulation tool called Drive Dynamics Analyzer (DDA) to be able to analyse dynamics features in rotating machines. DDA is written in Matlab and can be compiled and run as an ordinary application principally, but a few simulations are only working when DDA runs directly under Matlab.

The main goal of this thesis is to set up an on-line communication between a future client/customer, which is going to have a compiled DDA application, and ABB, which does the advanced simulations under Matlab. For this purpose Matlab Web Server (MWS) is acquired. The MWS makes it possible to deploy Matlab based applications over a network using standard web technology.

The thesis also includes installation, configuration and learning the new technology involved for developing with the MWS.

The result is a MWS application implemented in the client DDA, enabling advanced services over the web without having Matlab installed. A file is transmitted from the client through the MWS to Matlab for calculation and a file holding the result is sent back and the simulation is plotted in the client DDA.

Preface - Acknowledgement

This degree thesis was done at ABB Process Industries, department FVT, during the period December 2001 to Mars 2002, as a part of the education Bachelor of Science in Computer Science at Mälardalen University in Västerås, Sweden. Inger Bolin and Maria Borg performed the work.

We sincerely thank our supervisors Mats Tallfors at ABB Process Industries and Johan Stärner at Mälardalen...
